` T all 107mm t may concern i -Be it known that LFHILIB F. JACKSON,

a citizen of the .United States, `and a `resident of the city of New York, Stapleton, borough of Richmond, in the county of Richmond and State of New York, haveinvented a new and Improved,Indestructible and Collapsible Drinking-Cup, of which thefollowingifsa full,clear, and exact description,

This invention relates to improvements in ,s

drinking cups and more particularly to an improved indestrucible and collapsible drinking cup.

The specific objectief the invention is comprehended in, the provision`l of a cupto` be pressed or molded-of rubber or. other resilienti material or composition, to, lie Hat and thereby be rendered especially adaptable to be carried in ones pocket, and'l alsoreinforced at its edges to assist in itszas'sumption of a flat position -as well; ask to provide for increasing wearing qualities.

With the aboveiandother objects in view,` thev invention resides more particularly in; the peculiar combination and arrangement of parts which will be illustrated as a preferred embodiment in the accompanying drawings and described in the specification.

Reference is to be had to the accompanying drawings forming a part of this specioation, in which similar characters of ref erence indicate corresponding partsk in all the views, and in which- Figure 1 is a perspective view of one form of my improved indestructible and collapsible drinking cup with reinforced edges; Fig. 2 is a vertical sectional vewthereof; Fig. 3 is a plan view; Fig. 4 is a plan view of the cup when expanded or open; Fig. 5 is a perspective view of a modified construction in which a reinforcing and expandingwire or spring is employed; Fig. 6 is a vertical sectional view thereof; Fig. 7 is a plan view; and Fig. 8 is also a plan view but showing the cup in an open position. l

Referring to the drawings and more` particularly to Figs. 1 to 4 inclusive, it is here stated that the essential object of the invention is carried out in providing a cup of rubber or other resilient material or composition, pressed or molded into shape and constructed of a single section or piecey in such a way that the rubber or composition of which it is made will act to collapse or close the cup automatically but will .permit the cup to be crushed without being injured or carried inL ones pocket so that the person if will beunaware of its being there and with- Patented Nov. 3, 19:14,.

out ,the noise usually occasioned vbythe ordinaryftelescope cup.y yln said figures the numeral lindicates a drinking cup ofthe y material mentioned and which, when in col-l lapsed condition as shown inFigs. 1, 2 and;

3, its sideI portions r1-1 disposed .closely adiacent soas tolie/latkand occupy a minimuinspacathe generad shape being that ofl a sectork ofa circle having a round bottom portion 12 and having the free edges 13 con-y vexly arcuate so asto provide edge portions 14 reinfcrcedby a binding 15 inthe forniof an integral or separate reinforcing strip.-

By reasonfof the convexlyarcuate edge portions. 18, the cup lwill be caused to form opposite spout portions atV theedges 4 when theic'up isexpan'ded. i This binding extends continuouslyof the closed edge of` the'cup and results in an increases in rthe thickness.

thereof with increased added resiliency'7 i tending tozcausejthe kcup to assumega collapsed position, as well as to increase the "wearing qualities.y The rounded bottom also prevents the collection of sediment yin the bottomof the cup by insuring its thorough drainage, and by constructing the cup of odorless rubber or some flexible and water? proof material which may be extended, it is obvious that the cup mayy also be collapsed to occupy a minimum space when being carried and this without injury.

In the form of the invention illustrated in Figs. 5to S inclusive, the cup is of similar construction except that in lieu of the binding 15 the edge .portion of the cup is reinforced or thickened, as shown at 16, to provide substantially semi-circular kprojections when the ycup is open,` as shown in Fig. 8.

This rib or edge reinforcing thus provided i has mounted therein, `either4 molded or pressed with the cup or inserted after the cup is molded, a wire or other `spring 17 conforming in shape to the outline of the cup when in collapsed condition, its leg por# tions being normally spaced apart to exert outward pressure to" assist in the collapsing of the cup.

In either of the forms of the invention illustrated the cup may be expanded or opened by pressing against the edge portions to. cause the same to assume the positions illustrated in Figs. 4 and y8. `Owing to the fact that the spring employed in the structure` as shown inFigs. 5 to 8, inclusive i io is inclosed in the lid or edge reinforcing, contact of the water therewith and consequent rusting or corrosion and resultant contamination of the water or other beverage will be obviated.

Having thus described my invention, kwhat I claim as new and desire to secure by Letters Patent is l. A collapsible drinking cup consisting of a single continuous section of waterproof and flexible material held collapsed and adapted to he expanded by pressure against the top portions thereof when in collapsed condition, and a reinforcing binding continuously of the closed edge portion of the cup to resist the pressure for expanding the cup, said binding being unexposed to the interior surface of. the cup, the edges of the cup at the mouth portion being convexly arcuate to causev the same to assume spout portions at the opposite closed edges when the cup is expanded and the bottom of the cup being rounded to prevent the collection of sediment therein.

2. A collapsible drinking cup having opposed flat sides with a narrow connecting edge, the cup flaring toward its mouth portion to produce a substantially truncated member when expanded and opened, and a reinforcing binding around the edge portion vof the cup to strengthen the same and add resiliency to such edge portion to cause the cup to automatically assume a collapsed condition.

`3.y A collapsible drinking cup having opposed sides with a narrow connecting edge, said cup Haring toward its mouth portion and havingr a rounded bottom to prevent the 'collection of sediment therein when the cup is expanded or collapsed, the edge portion of the cup being increased in thickness to pro'- vide resilient reinforcements projecting from the exterior face of the cup, and a resilient member of a shape corresponding to that of the cup in side elevation, around which the material is'molded at the edge portion to embed the same therein spaced from the inner and outer faces of the cup, said resilient member serving to cause the cup to assume a collapsed condition by outward expansionI of its side portions and servinof as a reinforcement at the edge portion ofz5 the cup.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

PHILIP FREEMAN JACKSON.
